LED illuminating module heat dissipation and abating protection device

Abstract

The invention provides a heat radiation failure protection device of an LED illumination module. The device mainly comprises an LED lamp cluster, a power supply unit and a heat radiation fan; the heat radiation fan is connected on the main power supply circuit in series or in parallel, a controlling circuit is additionally arranged between the main power supply circuit and the heat radiation fan, and a current controlling component (like a field effect transistor, a three electrode tube, a relay, or a thyristor, etc.) is arranged between the controlling circuit and the main power supply circuit; when the heat radiation fan of the LED illumination module runs abnormally, the power supply current flow quantity of the main power supply circuit can be weakened or in an interruption state through the controlling circuit and the reaction action of the current controlling component, to lead the LED lamp cluster to be transformed and in faint light or power off state, and thereby achieving the protection effect of effectively preventing the over heated damage and the explosion of the LED lamp cluster, in order to further improve the operational safety and the quality of the LED illumination module, and to lead the LED illumination module to have the practical progression.

Description

technical field [0001] The invention relates to an LED lighting module, in particular to an innovative design capable of synchronously shutting down the LED or presenting a weak current state to produce protection when the cooling fan fails. Background technique [0002] LED lighting modules are currently widely used in various lighting and light-emitting display product structures due to their advantages of lower power consumption, longer service life and high illuminance compared to traditional light bulb structures. [0003] The LED lighting module, its LED light-emitting elements will generate a certain degree of heat when it is lit, the more the number of LED light-emitting elements configured in the module, the higher the total heat generated, and because the overall LED light-emitting The components are all assembled on the same substrate structure, so the heat cannot be completely dissipated through the air naturally, but is conducted to the substrate structure to co...

AI Technical Summary

Problems solved by technology

[0007] The invention provides a heat dissipation failure protection device for an LED lighting module, the purpose of which is to solve the problem that the LED lamp group is easily overheated and damaged, or even exploded when the heat dissipation fan is abnormal and the heat dissipation effect is lost
